CONNECTING-ROD.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed March 3, 1904. Renewed February 17, 1905. Serial No.246,018.

To all] whom as may concern:

Be it known that we, Ross M. G. PHILLIPS and J AMES A. WALKLEY, citizensof the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented a new and usefulConnecting-Rod, of

which the following is a specification.

This invention relates particularly to a connecting-rod designed for usewith an internalcombustion engine; and the main object of the inventionis to provide a novel construction of the crank end whereby the outerbrass and its retaining-block in the crank end may be adjusted by ascrew to take up wear or be readily removed, so as to leave a slotextending from the crotch clear to the end of the connecting-rod. Afterthe removal of the outer brass and its retaining-block the width of theslot thus formed is at least equal to or greater than the diameter ofthe crank-pin, so that the connecting-rod may readily be withdrawn. Thusit will be seen that the connecting-rod is especially adapted for use onengines in which the crank-pin is supported by double cranks or on anengine in which the crank-shaft, crank, and crank-pins are formed of asingle piece.

Another object of the invention is to provide a novel and effectivedevice for locking the retaining-block in place.

The accompanying drawings illustrate the invention, and referring to thesame Figure 1 is a side elevation of the connecting-rod, the crank endbeing shown in section. Fig. 2 is a section on line a c in Fig. 1, acentral portion of the crank being broken away to contract the view.Fig. 3 is a plan view of the crank end of the connecting-rod. Fig. 4 isan end elevation of the crank end. Fig. 5 is a perspective of theretaining-block. Fig. 6 is a perspective of a lock-nut. Fig. 7 is aperspective of one of the screws used for retaining one of the brasses.

l designates the shank of the connectingrod, which at the crank end isforked, as at 2, and one brass 3 is supported in the crotch of the forkby means of screws 4. The inner projecting ends of the screws 4 are 'cutor squared off, so as to form projections, the flat faces of whichsupport the edges of the brass 3, preventing it from slipping around,and the screws 4 are by the same construction prevented from unscrewing.The outer segmental brass 5 embraces less than half a circle, and thechord of its arc is not greater than the space between the two arms ofthe forked end of the connecting-rod. The brass 5 rests upon a saddle orretaining-block 6, which is provided with two slots 7.

The retaining-block 6 may be adjusted toward or from the other brass totake up wear by means of a nut 8, which engages screwthreads on botharms of the fork of the connecting-rod, as shown in Figs. 1 and 4. Thenut 8 is provided with perforations 9 for receiving a spanner-wrench toturn the nut and has a rim 10, which bears against the block 6.

After the nut 8 has been set to give the block 6 and its brass 5 theproper position the nut and block may be clamped securely by bolts 11,which pass through the forked end of the connecting-rod and through theslots 7 in the block 6. The nuts 12, which are provided on the bolts 11,may have notches 13 on their upper faces adapted to receive a wire 14,which is carried by a screw 15. The ends of the bolts 11 are alsonotched, as at 16, to permit the wire 14 to enter the notches in thenuts 12. By springing up the ends of the wire it may be turned with thescrew 15 acting as a swivel into the position indicated by dotted linesin Fig. 3, which will release the nuts 12, permitting theretaining-block6 and the nut 8 to be loosened for adjustment of thebrass 5 or removal of the block and brass.

We are aware that the crank ends of connecting-rods have been madeforked and that straps, wedges, &c., have been utilized for holding thebrasses in place and adjusting them fortakingup wear, and we do not,therefore, claim a forked construction broadly, but regard the screw inthe forked end for adjusting the block and brass, together with asuitable means for clamping the same, such, for instance, as thebolts'shown, to be new and of considerable value.

Other minor features of the invention which we consider to be within thespirit of our'invention are set forth in the claims.

What we claim is 1. A connecting-rod having a forked end, a suitablebearing device in the forked end, a screw in the forked end foradjusting the bearing device, and means for contracting the fork membersto clamp the screw.

2. A connecting-rod having a forked end, a bearing-block in the forkedend, there being separate but related screw-threads on the inneropposite faces of the fork, and a screw engaging said threads foradjusting the bearing-block.

3. A connecting-rod having a forked end, a slotted bearing-block in theforked end, there being opposite related screw-threads on the innerfaces of the fork, a screw engaging said threads for adjusting thebearing-block, and a bolt through the fork and slotted block forclamping the block and screw.

4. A connecting-rod having a forked end, a bearing-block in the forkedend having two open slots, there being opposite related screwthreads onthe inner faces of the fork, bolts through the fork and slotted blockfor contracting the fork, a screw in the fork engaging the threads foradjusting the block, a brass in the crotch of the fork, and screws inthe fork having protruding flattened ends which engage the edges of thebrass.

5. A connecting-rod having a forked end, a brass in the crotch of thefork, and screws in the fork having protruding flattened ends whichengage the brass.

6. A connecting-rod having a forked end, a slotted bearing-block in theforked end, there being opposite related screw-threads on the innerfaces of the fork, a screw engaging said threads for adjusting thebearing-block, a bolt through the fork and slotted block for clampingthe block and screw, a nut for the bolt, and means for locking the nut.

7. A connecting-rod having a forked end, a bearing device at the forkedend, suitable means in the forked end for adjusting the bearing device,and means for contracting the fork members to clamp the adjusting means.In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, at Los Angeles, in the countyof Los Angeles and State of California, this 24=th day of February, 190i.
